The invention relates to an outdoor GIS (Gas Insulated Switchgear) control cabinet. The outdoor GIS control cabinet is characterized in that the control cabinet is of a structure integrated with an intelligent control cabinet; intelligent elements and a GIS control element are arranged in different compartments; a loop connected with the GIS control element adopts a prefabricated aviation plug; a loop connected with an intelligent assembly adopts a prefabricated non-welding optical distributor; a temperature control device is arranged on the rear door of the cabinet; the bottoms of the compartments where the intelligent elements and the GIS control element are located are provided with prefabricated cable mounting plates; and the middles of the compartments where the intelligent elements are located are provided with prefabricated optical cable distribution boxes. With the outdoor GIS (Gas Insulated Switchgear) control cabinet of the invention adopted, the space of the intelligent control cabinet can be saved, delivery time can be shortened, and a requirement for plug and play can be satisfied.
